Parse::ExuberantCTags parses ctags files and handles both traditional
ctags as well as extended ctags files such as produced with Exuberant
ctags. It does not handle emacs-style "etags" files.

The module is implemented as a wrapper around the readtags library
that normally ships with Exuberant ctags. If you do not know what
that is, you are encouraged to have a look at
http://ctags.sourceforge.net/ and look at the exuberant-ctags
package.
